#0183;#32;If the gold and platinum are quot;freequot; (IE, not tied up with refractory minerals like arsenopyrite), by far the simplest way to separate gold and platinum from black sand is by gravity. There are many types of sluice boxes and spiral jigs commercially available, or you can build your own. Or you can use a
#0183;#32;2006. A. It was funny that I found what you wrote because I was looking for a solution to the exact same problem. I have an almost dry well on my property that I use for irrigation when watering by hand. 2 days ago I discovered black sand and fine gold in
27/6/2019#0183;#32;At least compare it to the black sand in a concentrate. That is the easiest way. Gold is extremely heavy and the best way to know if it is gold or not is to learn to separate the materials by weight. Get one of those little grains in your teeth and bite it. If it crushes it is not gold. If it dents under the pressure of a tooth it is gold.
2/12/2015#0183;#32;You can use a sluice box, a gold pan or other larger scale equipment, but much faster. All you need to do is ensure you are working the material enough to allow all the gold to get all the way to the bottom, then you can just wash the rest of the material away. No worries about larger material not being thoroughly washed or messing with the hydraulics so gold doesn''t accidentally get thrown away.
How to Remove the Flour Gold From Black Sand Our Pastimes. Separate the gold flakes from the solution by pouring it through a coffee filter Allow the solution to drip through to a third glass beaker The gold flakes will remain on the filter Fill the plastic tray with water to half of its depth, place the remaining circuit board scrap in it and rinse
#0183;#32;There are a few methods for removing fine gold from other sands. Panning is obviously the most common method using gold''s specific gravity to separate it from other lighter materials. The problem is that a speck of gold can be so small that is is actually lighter than a larger piece of the overburden you are trying to recover it from.

Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that onceinalifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from
4/9/2019#0183;#32;How to process black sand concentrates is a big deal and it frustrates many new prospectors and old ones as well. The goal is to get a clean gold placer that...
(2) Once the gold is dry, bring it inside, out of the wind, and pour it onto a piece of clean paper. You can now pick out the larger impurities from the gold with tweezers. (3) Now a magnet can be used to extract most of the remaining black sands for you gold. I use a super magnet, but I used to use the Keene Gold
#0183;#32;Simply put gold and sand into mercury. sand would float to the top and gold would sink down. However, please never use this method to separate sand and gold. Mercury and its vapor are very poisonous. Mercury may also seek into SiO2 sand and make the contaminated sand
It uses a simple design of circulating water (much like a flushing toilet) to separate any lighter material and black sands while keeping the gold at the bottom of the bowl. Other popular equipment include spiral panning wheels, which use a specially designed spiral motion at an exact angle to capture the fine gold.
At this stage, youll want to pull the black sands and gold from the blonde sands. Its okay if a small portion of the blondes are drawn up along with the blacks in this first split. We have found that skimming the lighter sands off the top of the material being
Black sand is often mostly magnetite. Get a good magnet and you can pull the magnetite out easily. Put a piece of paper over your magnet, otherwise you will have difficulty in getting the fine magnetite cleaned off of it. You can then separate the...
Removing the small gold particles from the black sands . After a prospector has spent all that time and effort getting to this point in the process, they certainly dont want to leave it up to chance to get all the gold out of the concentrate; many times if gold is present in the black sands it

#0183;#32;If gold is physically bound to minerals, it can sometimes be separated by the application of heat in a smelting operation. At other times, the only way to separate the gold is to immerse quantities of black sand in chemical baths a process called wet chemical extraction.
how to separate the gold dust from rock combined of gold. May 11, 2007 Gold dust is separated from auriferous sands by gravity. The auriferous sands are washed with water in a gold pan or sluce. Since the gold particles are much heavier than the sand they settle to the bottom of the pan or sluce.
